Re: [問題] JTable存檔讀檔的問題
by the way, if you wanna store a TableModel instead of JTable,
please make sure that
your tableModel class (which extends AbstractTableModel i presume)
had implements Seializable
and all it's declared variables (except primitive type) are
Serializable classes as well.
Another alternative is (If you are lazy to implements your tableModel
as serializable) , declare your variable as AbstractTableModel
but comes to the consequence that methods of its subclassed you can't
access anymore.
e.g. :
AbstractTableModel table = new YourTableModel();
objectOutputStream.writeObject(table);
